IMPROVEMENT IN DEVICES FOR HOLDING SPINNING-BOBBINS 0N SPINDLES.

Specification forming part of Letters Patent No.l 116,168, dated June 20, 1871.

To all whom t may concern:

Be it known that I, GEORGE DRAPER, of Hopedale, ofthe county of Vorcester and State of Massachusetts, have made a new and useful invention having reference to the Spindles and Bobbins of Spinning-ll/Iachines; and do hereby declare the saine to be fully described 1n the following speeiiioation and represented in the accompanying drawing, of Which- Figure 1 is a side elevation, Fig. 2 a vertical section of a spindle and bobbin provided With my invention. Fig. 3 is an elevation of the spindle, the whirl, and the friction-bobbin supporter as they appear without the bobbin.

The spindle Ain this case is what is termed a dead spindle, the whirl B being revolvable on and arranged on such spindle in manner as shown. Below the whirl is a collar or bearing, a, which is fixed on the spindle so as to extend a little above its sumporting-rail. Projecting up from the whirl, and encompass ing the spindle, is the friction-bobbin support er C, which in this instance is represented as a tube, b, and a series of leather or caoutchouc washers, cc c, arranged on or about the tube and one another, and coniined on it and together by a cylindrical clamp-nut, (l, screwed upon the upper end of the tube. Just above the friction-bobbin supporter there is a stopcollar, D, arranged on the spindle, and iixed to it by a set-screw, e. The bobbin, shown at E, has two bores, fg, the lower one being to t to or closely upon the frictionbobbin supporter, the other being to receive that part of the spindle which is above the stop-collar, the spindle at its upper end or part being pivoted in the head or upper part of the bobbin, which,

as shown in the drawing, is provided with a metallic step, h, to receive the upper end or pivot fi of the spindle. This step revolves with thebobbin, and serves to support it on the head of the spindle, the spindle being revolved. by the whirl and the friction-bobbin supporter while they are in revolution. The bobbin is to fit closely upon the elastic friction-bobbin supporter so as not only to enable the latter to revolve the bobbin, but to steady it so as to prevent it from vibrating the pivot and step at the heads ofthe spindle and bobbin, serving, also, to sustain the bobbin and prevent it from vibra-ting. The object or purpose ofthe stop-collar D is to prevent the whirl and the frictionbobbin supporter from being drawn off the spindle by the bobbin during an attempt to remove it from thenl.

What I claim as my invention is as follows:

1. In combination with the dead spindle A and its Whirl B, the friction-bobbin supporter O, extended from and above the whirl and on the spindle, and constructed substantially in manner and for operation with the bobbin and spindle, as described.

2. In combination with the subject of the above claim, the bobbin and spindle-pivot t' and step h, or the equivalent thereof, arranged at the heador upper part of the bobbin, as set forth.
